Hello,

I am running a Lagrangian simulation and instead of making a really large domain would like to have non-reflecting boundary conditions to assume an representative volume element in infinite space. I know there is a non-reflecting boundary in MMALE, but am aiming to do this in traditional FEA with solid hex elements.

Thanks,

Peter

LS-DYNA has the perfectly matched layer (PML) absorbing boundary. Please see the links on PML on this page:
